The recombinant peptide Cellnest increases the engraftment rate of administered cells by forming a complex with the cells (CellSaic). We hypothesized that CellSaic containing adipose-derived stromal cells (ADSCs) could improve lower limb blood flow better than ADSCs alone, resulting in better transplanted cell engraftment. ADSCs were extracted from 8-week-old C57BL\/6N mice. Thirty-two critical limb ischemia model mice were established by ligating femoral arteries. They were divided into CellSaic (<jats:italic>n<\/jats:italic>\u2009=\u200911), ADSC (<jats:italic>n<\/jats:italic>\u2009=\u200910), saline (<jats:italic>n<\/jats:italic>\u2009=\u20099), and Cellnest (<jats:italic>n<\/jats:italic>\u2009=\u20099) groups. Blood flow rate (affected side blood flow \/ healthy side blood flow\u2009\u00d7\u2009100%) was evaluated using a laser Doppler blood flow meter every week. Mice were euthanized on day 28 for histological evaluation. Compared with the ADSC group (54.5\u2009\u00b1\u200917.2%), treated side blood flow rate of the CellSaic group (78.0\u2009\u00b1\u200924.9%) showed significant improvement on day 28 after administration (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.05). CD31 staining showed significantly higher number of capillary vessels in the CellSaic group (53.0\u2009\u00b1\u20098.9 cells\/mm<jats:sup>3<\/jats:sup>) than in the ADSC group (43.0\u2009\u00b1\u20096.8 cells\/mm<jats:sup>3<\/jats:sup>) (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.05). Fluorescent staining showed significantly higher number of arterioles containing both CD31 and \u03b1SMA double-positive cells in the CellSaic group than in the ADSC group (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.05). CellSaic containing ADSCs exhibited superiority to ADSC transplantation alone in promoting functional angiogenesis, suggesting its potential in improving clinical outcomes of angiogenic therapy for ischemic limbs.<\/jats:p>","DOI":"10.1007\/s10047-021-01254-8","type":"journal-article","created":{"date-parts":[[2021,3,3]],"date-time":"2021-03-03T11:03:54Z","timestamp":1614769434000},"page":"343-350","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["New cell delivery system CellSaic with adipose-derived stromal cells promotes functional angiogenesis in critical limb ischemia model mice"],"prefix":"10.1007","volume":"24","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8892-144X","authenticated-orcid":false,"given":"Hideki","family":"Tanioka","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shigeru","family":"Miyagawa","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daisuke","family":"Mori","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ken-ichi","family":"Watanabe","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takayoshi","family":"Ueno","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Koichi","family":"Toda","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takashi","family":"Shibuya","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Toru","family":"Kuratani","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yoshiki","family":"Sawa","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2021,3,3]]},"reference":[{"key":"1254_CR1","doi-asserted-by":"crossref","unstructured":"Norgren\u00a0L, Hiatt\u00a0WR, Dormandy\u00a0JA, Nehler\u00a0MR, Harris\u00a0KA, Fowkes\u00a0FGR, TASC II Working Group.
